SPECIFICATION forming part of Letters Patent No.3l6,l52, dated April 21,1885.

Application filed January 6, 1855. (X0 model.)

riage and the top of the doorway, consists, in

brief, of a light movable frame, with an edge arranged to extend fromside to side of the doorway, and in such proximity to its inner top edgeas to interceptand be moved by anything projecting from the edge of thelift which would otherwise come against the top of the doorway,intermediate mechanism converting the motion of this frame to themovement of a clutch-section splined upon a spindle having a crank-armupon one end, a corresponding clutch-section revolving loosely andconstantly driven by power upon the same spindle, and an arm arrangedupon the starting and stopping rod of the elevator to adapt it to belifted with the rod by the crankarm of the clutch-bearing spindle uponits first rotation. V

My invention also consists in mechanism for conveying the motion givento a movable contact-bar upon either side of a doubledoor elevator to acommon {clutch for operating the stopping-rod, and in devices foroperating one clutch from any doorway of any floor of a building withoutrequiring any contact-bar to lift the Weight of any connection to theclutch but of that or those immediately below it.

The construction of my invention is fully illustrated in theaccompanying drawings, in which- Figure I is a side view of a portion ofan elevator with a part of one side broken away. Fig. II is a view ofthe same as seen from an other face, and Figs. III, IV, and V aredetails.

B is a light frame, hung in bearings 12 b from the ceiling outside ofthe elevator.

D is the contact-bar, forming one side of frame B, extending from sideto side of the doorway, as seen in Fig. I, and coming close to the pathofthe edge of the liftWand nearly below the top of the doorway, as shownin Fig. II.

a is a stop to retain the frame B in a horizontal position.

e is an arm from the side of frame B. The arm a is received in a loop ofrod E.

The rod E is connected by a link, f, to the 1 0 The spindle I has uponone end the crankarm J, as shown in Figs. II and-V, and has also uponit, between one hanger O and the clutch-section H, the correspondingsection, L. The section L is also a loose pulley driven constantly bythe belt P.

M is the rod common to elevators, and within the well, by which theoperator, by pushing down on a handle, as Y, Fig. I, starts theelevator, or by pulling it up stops the same. This rod has arranged uponit,so as to project through a slot in the wall of the elevator, (notshown,) an arm, V, to come within the circle described by the crank-armJ in a rotation,

and the arm V is so relatively placed to the crank-pin J as to cause itto be lifted by the latter the distance required to stop the upwardmovement of lift W as the same movement of rod M would through itshandle Y.

In operation a slight contact of anything upon the ascending lift WVwith the bar D raises it upon its hinges b b, to carry with it the rodE. The rod E, through link f, bellcrank g, and toggle t and shipper m,throws the clutch into operation to, through crank J and arm V, lift rodM to stop the ascent of the lift WV. Any movement of frame B isinstantly conveyed to the clutch-section H, which has only a shortdistance to move before engaging With the rapidly-revolving pulley, andthe rod M is lifted to stop the elevator much quicker than it could bemanually.

The weight of the frame B and its connections, while enough to unshipthe section H when released by an obstacle raising it, is in sufiicientto hurt any one dragged against it,

. and can be made sensitive enough to be operated by the projecting toeof a shoe.

The operating-rod M of an elevator is made to remain in one positionuntil deliberately moved, so that when once lifted the elevator isstopped, the clutch is released, and the crankpin J returned to itsposition by its weight, all as seen in Fig. II.

In an elevator having opposite doors the rod E is hinged at its lowerend to the crankarm 76 of a rock-shaft, K, carried without the casing orwall of the elevator, or through it at a point which will not be in thetrack of the lift 7..

The rock-shaft K is hung in bearings, and from a correspondingcrank-arm, 7;, on its other end a rod, E, is connected by being loopedover an arm, 6, of a duplicate frame, B, so that any movement of theframe B upon this side is conveyed to the clutch, while any movement ofrod E leaves the frame looped to rod E uninfluenced.

Upon every doorway of every floor I arrange frames B, hung as shown inFig. II, and connect the frames flexibly, as shown, by the chains 00 x,with those immediately below, by means of which arrangement,while anyframe will be operative to lift rod E or E to throw in the clutch, noweight will have to be lifted above any frame B.

Without a departure from the spirit of my invention the crank J may bemade to depress arm V to stop the motion of the lift W, should the rod Moperate in the reverse manner from that common.

Now, having described my invention, what I claim is- 1. Thewithin-described improvement in elevators, consisting of a movable bar,D, arranged in the doorway in close proximity to its top and the trackof a lift, W, a clutch consisting of a splined section, II, a spindle,I, hung in bearings O O, and a constantly-revolving loose section, L, acrank-arm, J, upon spindle I, an operatingrod, M, having an arm, V,adapted to be moved by crank-arm J, and mechanism, substantially asshown and described, for connecting bar D and clutch-section H, and forconverting a movement of the former to a motion of the latter, for thepurpose set forth.

2. In an elevator, the combination,with two movable frames, B, havingbars D, supported in position to intercept a projection from lift WVbefore striking the top of the doorway, and arranged upon oppositedoorways, of rods E E, framed to crank-arms la is from shaft K, andadapted to convey a movement of the frame B upon either side to themechanism operating the stop ping'rod M, substantially as shown anddescribed.

3. In an elevator, the combination, with rods E E upon oppositedoorways, and adapted upon an upward movement to operate mechanism formoving rod M, and so stopping the elevator, of superimposed frames B,arranged to operate as shown, and flexible connections from said framesto rods E E, adapt ed to be operative upon a movement of frames B, tolift only the connections interposed between said frames and the rodsbelow the same, for the purpose as set forth.
